Hi all,
I'm getting frequent system crashes (every few hours or so) and it seems that the nouveau driver is causing the issue (dmesg output below). I see it with both v5.2.8 and the v4.19 LTS kernel. Sometimes the system completely freezes and sometimes seemingly just the nouveau driver goes down. The screen freezes and colours stream across it. Often after I reboot the BIOS logo is mangled too until the first modeset. The crash seems to be happening in nv50_fb_intr() in nv50.c.
I'm not sure if this is related, but the system now often freezes on suspend or resume since I switched from using the old (recently abandoned) proprietry NVIDIA drivers, again both with 5.2 and 4.19 kernels. Blacklisting the nouveau driver doesn't seem to fix it however, though I guess the graphics card could still be causing issues in some other way? I never had problems with suspend and resume before.
Any suggestions about how I could debug this further?
Is it really a software problem (does it still work fine with proprietary driver)? These nVidia chips are known to fail and corrupt BIOS logo suggests that.
